No land plants in the deepest rock layers. Water plants are easily covered with sediment while land plants rot long before sediment covers them usually.
Some paleontologists specialize in the study of particular organisms. Invertebrate paleontologists study animals without backbones, whereas vertebrate paleontologists study animals with backbones. Paleobotanists study fossils of plants. Other paleontologists reconstruct past ecosystems, study the traces left behind by animals, and piece together the conditions under which fossils were formed. As you see, the study of past life is as varied and complex as Earth's history itself.

This all depends; Paleontologists are usually in an office, or, they are out doing field work. If they are in an office this could also mean in a classroom, seeing a lot of paleontologists work as university professors.
If water plants lived in an area of volcanic hot springs such as Yellowstone Park, the silica in the water would gradually be absorbed into the cells of the plants. This kills the plants over time but it also preserves their structure in a rock called chert. The 410 million year old Rhynie Chert in Scotland is a good example of early plants preserved in this way.
dead organisms get buried in dirt,sand,etc which harden and turn into rocks over a long period of time.

they've learnt that ferns are one of the oldest plants still in existence. and plants started off as algae-like organisms.
A biologist studies both plants and animals. A taxonomist classifies both plant life & animal life.
The hardened remains of plants and animals are typically bones or fossils. Fossils are the hardened remains that are formed due to pressure from being squished between Earth's layers.

A paleontologist is a scientist who studies fossils to learn about prehistoric plants and animals.
